Have you experience a headache to the point that you want to bang your head on the wall? Yes, last week I had a very terrible headache! I am already taking a Migraine drug free but still the ache didn't disappear until I got slept without my notice and thanks God when I woke up I don't have headache anymore. I never changed my eyeglasses yet for three years and I guess that's the very root of my headache. My eye grade kept on increasing and I really need a new glasses now but due to lack of budget I must use it util I'll have a new one.
